Two-way communication channel
proposed by Lim and Rizos (
2008
). The main goal of the framework was to
integrate information and communication technologies, database and web tech-
nologies, and GPS CORS network infrastructure, to upgrade the capability of the
server to real-time data processing. These augmentations enable the servers to
carry out data management and spatial analysis, and at the same time creating a
platform for the users to efficiently utilize the results. Zinas et al. (
2012
) present an
enhanced processing strategy by combining a single-baseline and a multiple rover
network solution in a centralized (server-based) GNSS architecture. The main goal
of this study was to use the shorter inter-receiver baselines to improve the results
of single-epoch ambiguity resolution.
Some of the advantages of combining the server-based processing concept and
two-way communication in the reverse approach include (Rizos
2007
; Zinas et al.
2012
):
• Control of the products is vested with the service providers.
• Quality of service is guaranteed.
• Increased value on product, and enhancement of commercial value on the
service.
• The user is relieved from the burden of complex computations.
• Low-cost receiver hardware can be deployed for field data streaming.
• Multiple users can be supported simultaneously.
